C # monitoring which have the external device inserted into the USB port-CodePudding

If it is a desktop application, you need to form the system message interception WM_DEVICE_CHANGE, then determine which devices are connected to the system,

 
Protected override void WndProc (ref Message m) 
{
Int WM_DEVICE_CHANGE=0 x219 

//here only handle WM_DEVICE_CHANGE message 
If (m.M sg!=WM_DEVICE_CHANGE) 
{
Base. WndProc (ref m); 
return; 
} 

//write your processing logic below... 
}

Thank you, this is to monitor hardware devices have change, but how to know is which a device inserted into the USB port

Not, is inserted into the usb device corresponding port

Do you know how to achieve it, I asked some people, they said using Win32 API, but I don't know how to do

CodePudding user response:

You plugged into the USB port will not have a name, it just is a serial bus, USB device information, you can get the most is if you want to get to the USB serial number of the serial port of simulation is possible
